Aiman Samat made it fair and spectacular for Glockzilla.
If you're a Godzilla sympathizer, you'll like Aiman Samat's decision to give it "an upper hand" in the form of a gun. Glockzilla is not just effective, it's glorious in its emergence from the 3D waters, set up with Blender's FLIP Fluids and EmberGen.
The model was created by Owen Kellen, with the animation done by Fiona Ho. Samat wanted to test out a large-scale water simulation with Blender and FLIP Fluids, but it eventually turned into a whole mini-trailer.
